SARS-CoV-2 antibody test
Antibody Post Test for SARS-CoV-2
Rapid test to detect IgG antibodies to SARS-CoV-2.
- Lateral Flow Rapid Test
- qualitative detection of IgG and IgM antibodies in human whole blood (venous and capillary blood), serum or plasma
- approved for use by trained personnel
- Results on site within 15 minutes
- already approved in the EU
- available in large quantities
Benefits of the test
- IgG antibody tests for SARS-CoV-2 can reveal the dark figure of corona cases (as the Austrian Federal Government also demanded in its press conference on 24.03.20)
- People who have already been infected with the SARS-CoV-2 virus have IgG antibodies to this virus in their blood, which can be detected by the test.
- According to the current state of science, these people are then immune to the SARS-CoV-2 virus and can no longer endanger other people.
- The test therefore offers the possibility to identify people who were already ill and can now no longer cause infection.
- This enables companies to identify employees who can be reused for customer contact, but also those who can carry out their daily business in a fully regulated manner at their designated workplace.
- All this leads to the fact that many things in our society can quickly return to normal and contributes to slowing down the pandemic
How does the test work?
- Collect 20µl whole blood (or 10µl serum/plasma) from the fingertip
- Applying to the test strip
- Applying the buffer solution
- Read the result after 10 minutes
The test is only approved for trained personnel!
Sensitivity and specificity:

Scope of delivery
- Test stripe
- Buffer solution
- Sterile safety lancet
- Test instructions
Antibodies and Immunity
IgG antibodies are produced at the latest 14 days after an infection – but are extremely important for the “memory” of the immune system. This is because they are used later, when there is renewed contact with pathogens (bacteria, viruses).
As soon as IgG antibodies can be detected in the blood, it is assumed that SARS-CoV-2 can neither be transmitted nor can it break out again within the next few months.
IgM antibodies are formed the first time the body comes into contact with a certain pathogen and serve as the body’s immune response to foreign substances in the body. IgM antibodies point to an acute infection.
IgG antibodies are – after the IgM immune response of the body – the most produced immunoglobulins in the body in response to the viral antigen. They are used as long-term proof of infection with SARS-CoV-2 and COVID-19 infection. With IgG antibodies formed, the current state of knowledge assumes that the patient is immune to the virus.
Course of the coronavirus
- 80% mild to moderate course
- 14% severe course
- 6% critical to life-threatening
on average 5-6 days (range 1-14 days)
Risk of infection:
max. up to 8 days after onset of symptoms
(until viruses capable of reproduction are no longer present)
In fact, only 50-80% of all infected people fall ill (but are still carriers)
estimated by Chinese studies that only 5-10% of all cases are recorded
It is assumed that people cannot become infected several times within a short period of time = immunity after recovery.
